Be it known that we, FRANK C. HINCKLEY and JOHN J. ScuLLY, citizens ofthevlUnited States of America, and residents of Bridgeport, Connecticut,have invented a new and useful Improvement in Automatic Stops, whichinvention is fully set forth in the following specification. a

This invention relates to stop mechanism, and particularly to stopmechanism-espa cially designed for use in talking machines.

In machines of the latter type, a soundboX operatively connectedto asound-conveying member, which together, will here ferred to as atraveling element,, has move ment relatively to arotary record-support,which support, or any other suitable motor driven member, will bereferred tohereafter as a rotating element, the sound-box andsound-conveying member Igenerally being fed across therecord-support bythe coaction of the former with thegroove in the sound-record tablet. Itis an object of this invention to provide a stop mechanism of improvedconstruction, whichshall stop the rotation of the record-support orother rotating element upon the completion of the traverse of thesound-box and sound-com veyin member. i

A further object of this invention is to provide stop mechanism of thecharacter referred to, with improved means whereby a predeterminednumber of revolutions of the rotating element must occur before saidstop mechanism can come into; :action, whether the traveling element bestationary or not. I a i i A still further object of the invention is toprovide a stop mechanism of the type characterized with amanually-operable controlling member by which the machine may be stoppedat any time independently of the mechanism for automatically stoppingthe same. a c

Yet another object of the'invention isito provide a stop mechanism ofthe type characterized for use in connection with a motor hinged to itssupport, whereby the motor may be swung into and out ofits normalposition without the necessity offmanually connecting and disconnectingthetparts of the stop mechanism respectively connected to the movablemotor and the stationary support.

. Other objects relate to the provision of a stop mechanism of 5 thetype in question which is simple in construction inexpensivetomanufacture and install and efiicient in operation. H Stated broadly,the invention comprises, in combination, a rotating element, a travelingelement, stop mechanism, a member for actuating the same shown as, arotating member, means operatively connected withthe rotating elementfor movingsaid member into stop-actuating position, and meansoperatively connected with the traveling element for preventing themovement of said member into stop-actuating position while the travelingelement continues its traverse, said stop mechanism being controlled bya member, shown as a detent, and preferably both pivotally and bodilymovable, which coacts with said stop mechanism to move said controllingmember out of operative relation with said actuating member uponactuation of said stop mechanism. Preferably a predetermined number ofrevolutions of the rotating element must occur before said actuatingmember comes into approximate stop-actuating position, said meansoperatively connected with the traveling element thereafter, and so longas the traveling element continues its traverse, preventing saidactuating member from moving into final stop-actuating position. Saidstop mechanism, which may be either abrake or a switch, is operativelyconnected with a main ual controlling member for moving said stopmechanism into starting position, and a manually-operable member is alsopreferably provided for effecting the actuation of said stop mechanismindependently of the automatic mechanism above referred to.

The invention is capable of receiving a variety of mechanicalexpressions, one of which is shown on the accompanying drawings, but itis tobe expressly understood that the drawings are'for purposes ofillustration and are not to be construed as a definition of the limitsof the invention, reference being had to the appended claims for thatpurpose. I i

In said drawings Fig. 1 is an end view of a talking machine providedwith automatic stop mechanism in accordance with the present invention;

Fig. 2 is a, plan view of the stop mechanism, showing the machinestopped but, for convenience, the stop-actuating member in the positionit assumes during the normal operation of the machine;

Fig. 3 is a fragmentary plan, parts being omitted for the sake ofclearness, showing the machine in operation and the stop-actuatingmember in an intermediate position;

Fig. 4 is a detail perspective of the brake lever and its controllingmember;

Fig. 5 is a fragmentarydetail perspective of the motor-drive of theactuating member; and

Fig-(Sis a'perspec'tive view of the manually-operable stop-actuatingmember.

Referring in detail to said drawings, wherein the same referencecharacters designate corresponding parts in the several. figures, 1represents the driving spindle of a rotary record-support 2 designed tocarry the usual record-tablet, and 3 the usual sound-box connected tothe tone-arm 4 suitably mounted on the talking machine casing as by abracket 5, said tone-arm being mounted in any suitable way to enable thesound-box to traverse a record on said support.

Frictionally connected to the tone-arm in any suitable way is an arm 6provided at its outer end with an operating nose 7 engaging in the slotprovided by the bifurcated end 8 of a lever 9pivota'lly mounted at 10 onthe motor-board 11. The opposite end of said lever 9 is provided with anoperating nose 12for a purpose to be explained hereinafter. To'limit themovement of said lever, a pair of adjustable stops 13 may be threadedinto lugs 14 carried by the motorframe 15.-

Rotatably mounted on the motor-frame at 16 is an actuating member 17shown as a gear provided with a'plurality of radial teeth 18. Carried bysaid member 17 is a pair of lugs 18- and 19, one or both of which aredesigned to coact with the operating nose 12 of the lever 9 and with acontrolling member to be described. Suitable means are provided forpositively and intermittently rotating the member 17 from the motor ofthe machine. In the form shown, a pinion 20, meshing with a gear 21 inthe drive of the spindle 1, is carried by a stub shaft 22 upon which ismounted a rotary pawl shown as provided with a single tooth designed toengage the teeth 18 of the member 17 and rotate the latter through adistance equal to the pitch of the teeth.

Pivotally mounted on the motor-frame at 24 is a brake lever 25 providedwith an operating arm 26 and, in-the form shown, with a depending arm 27carrying a brake element 28 designedto engage the usual brake disk ofthe talking machine governor. It is toibe expressly understood, however,that the invention is not limited to the use of a brake pad, as a switchmight be operated by said lever 25, nor to the application of the brakepad to the governor disk, as by suitable variation said brake pad mightengage other rotary members driven from the motor. The inner end oflever 25 is provided with a nose 29 for coaction with a controllingmember to be presently described, said lever being normally drawn intooperative relation with said controlling member by a spring 30 connectedat one end to lever 25 and at its opposite end to a pin 31 suitablyprovided on the motorframe.

Pivotally mounted on a pin 32 carried by the motor-frame is acontrolling member 33 which, in the embodiment of the inventionillustrated, performs the function of a detent for the brake lever 25.Said detent 33 is also mounted on the pin 32 for vertical bodilymovement longitudinally of said pin. Detent member 33, which may bedesirably made by bending the same up from a form struck out ofsheet-metal, is provided with an operating nose 34 designed to coactwith one or both of the lugs 18 and 19 projecting upwardly from themember 17, with an car 35 designed to coact with the brake lever 25 andmaintain the same in inoperative position, and with a cam surface 36shown as an arm bent upwardly, then inclined downwardly and forwardly,and then inclined again upwardly to a point slightly in advance of theear 35. A spring 37 suitably connected at one end to the detent member33 and atits opposite end to a pin 38 carried by the motor-frame,normally retains said member in its lowermost position and in engagementwith an adjustable stop 39 threaded into a lug 40 provided on themotor-frame, said spring, however, permitting both pivotal and verticalbodily movement of said member.

For starting the machine, a starting lever 41 is pivotally mounted onthe motor-board 11 at 42 and provided with an operating nose 43 designedto engage the arm 26 of the brake lever 25. A spring 44, suitablyconnected to the starting lever 41 at one end and to a pin 45 at itsopposite end, normally maintains said starting lever at the end of itslimiting slot in the position shown in Fig.2;

Means are also preferably provided to enable the manual actuation of thestop mechver 46 is shown pivoted to the motor-board at 47, said leverbeing provided at one end with a finger-piece 48'projecting through aslotin the motor-board and at its opposite end with an operating nose 49designed to engage and rotate the detent member 33.

reac es In the form of the invention shown, the motor. is mounted formovement into and out of its normal position about a hinge as shown inFig. 2. Owing to the relation of the end 7 of arm 6 and the bifurcatedend 8 of lever 9, said lever may move with the motor into and out ofoperative engagement with said arm without requiring manual connectionor disconnection of the parts constituting the train of mechanismbetween the tone-arm and the stop-actuating member 17.

To start the machine, lever i1 is swung from the position shown in Fig.2 to the position shown in Fig. 3 against the tension of spring 4st.During this movement, operating nose 4E3 engages arm 26 of lever 25 andmoves said lever against the tension of spring 30 until nose 29 on saidlever is moved out to a position wherein spring 3'? may snap ear 35 onmember 38 behind said nose 29 to retain the stop lever in off position,as shown in Fig. 3. As nose 29 is moved outwardly, the detent member isalso drawn downwardly by the spring 37 as fast as is permitted by thecoaction oi the inclined end of arm 36 with said nose 29.

Brake element 28 being new withdrawn from engagement with the governordisk, the motor starts and rotates the spindle l and record-support 2.Gear 21 rotates gear 20 and, through shaft 22, the rotary pawl 23. Ateach rotation, said pawl engages one of the teeth of the stop-actuatingmember 17 and advances the same through distance equal to the pitch ofthe teeth. In order to advance the lugs 18 and 19 on said member [7 fromtheir position when the machine is stepped into ope 'ative relationshipwith nose 12 of lever 9 and nose 34: of detent the member 1'7 must makehalf a revolution. While said member is making this one-halt revolution,ample time is provided for the positioning oi" the sound-box inoperative relation in the outer-groove of the record tablet. Thus,assuming that there are twenty teeth on the member 17 and that gear 20makes one revolutioi'i :tor each seven and a halt revolutions of theturntable spindle, it will require seventy-five revolutions of theturn-table before the lugs on member 17 are advanced into operativerelationship with lever 9 and detent It is to be expressly understood,however, that the invention is not restricted to the use of twenty teethon the member 1'7 nor to the lapse of one-halt a. revolution of saidmember before it assumes operating relationship with the lever 9 anddetent 33, as any suitable numberot teeth may be employed on said memberand, by suitable variation the lapse of time be- .t'ore said memberassumes operative relationship with the lever and detent may be lessthan one-half a revolution or as much as a whole revolution.

The sound-box having been operatively engaged with the sound-recordtabiet during the period when member 17 is making ahalt revolution, thesound-box and tone-arm now traverse the record and, through thetriotional connection betweenthe tone-armiand the arm 6, tend to drivesaid arm in a clockwise direction. Operating nose 7 on said arm 6 byengagement with the bifurcated end 8 of lever 9 tends to drive saidlever in anti-clockwise direction. The extent oi movement of said armand lever is, however, limited by the engagement of said lever with oneof the stops 1.3. Thereafter, until member 17 has been advanced inclockwise direction through one-halt a revolution to approximatelystop-actuating position, the arm 6 will slip with respect to thetone-arm a. When one of said lugs 18 or 19 is advanced intoapproximately stop-actuating position, it engages the operating nose 120t lever 9 nd moves said lever in a clockwise direction, id lever movingarm 6 in an anti-clockwise direction, which movement is permitted by thefrictional connection between said arm and the tone arm. After pawl 23moves out of engagement with said member 17, and while it is making itsrotation to the next tooth of said member, arm 6 driven by the tone-armmoves lever 9 in an anti-clockwise direction and, through its engagementwith the lug on member 17, rotates the latter in a clockwise directionadistance equal to the pitch otthe teeth. Pawl23 then coming intoengagement with the tooth on said member moves the latter in ananti-clockwise direetion an equal distance. Thereafter, and so long asthe traveling element continues its traverse, member 17 is subjected tothe intermittently and oppositely acting impulses of the lever 9 and thepawl 23, whereby it oscillates in opposite directions through alimitedare. Throughout this period the other of the two lugs 18 and 19 on themember 17 is in approlrimately stop-actuating position just out ofengage ment with nose 3& of detent 33. When the tone-arm ceases itstraverse, lever 9 is no longer moved in an anti-clockwise direction tomove member 17 in a clockwise direction. Said member therefore remainsin the position to which it has been moved by the pawl 23, whereupon atthe next engagement of pawl with member 17, said member is in ananti-clockwise direction advanced through a further distance to engagethe lug thereon with nose 84- ot detent 33 and swing the latter aboutits pivot 81 against the tension of spring 37. Thereby car 35 is drawnfrom engagement with nose 29 of lever 25 and. said lever is drawn by thespring 30 along the cam face of arm 36 until brake element engages thegovernor disk. Owing to the coaction of nose 29 with the cam or inclinedsurface of arm 36, detent 33 is moved upwardly along its pivot pin31-nntil nose 34 is freed from the lug or member 17 in engagementtherewith, whereby said lug may pass by said nose. The controllingmember 33 being thereby moved out of operative relation with thestop-actuating member, the latter is in position to make a halfrevolution upon again starting the machine and before the lugs on saidmember resume operative relationship with the lever 9 and member 33.

If it is desired to stop the machine prior to the automatic actuationthereof, or in case the automatic mechanism should not operate, themachine may be stopped by pressing inwardly on lever 4:6 until nose 49engages detent 33 and moves the same about its pivot to release stoplever 25 in the manner just described.
